One of the primary means of achieving global competitiveness is to reduce the COPQ in our business units. Although the COPQ is not known precisely, it is known to be very high. Also, it may be underestimated by the hidden costs due to non-value added activities, such as potential lost sales, costs of redesign due to quality reasons, and extra manufacturing costs due to defects, etc. In any manufacturing or service operation, all actions and resource expenditures of a company should be focused on creating value for customers. Any activity or resource of not creating the value for customers could be regarded as waste, which consequently causes the COPQ. In this paper, a management system is developed for evaluating and reporting the COPQ in our business units, based on the Six Sigma DMAIC (Define, Measure, Analyze, Improve, Control) roadmap.
